ABSTRACT
Objetivo: Determinar la incidencia, principales indicaciones y complicaciones de la histerectomía obstétrica (HO) en un hospital de segundo nivel de atención a cuatro años de implementar el programa de prevención y manejo de la hemorragia obstétrica. Método: Estudio de tipo descriptivo de revisión de expedientes clínicos, de tipo transversal, analítico y retrospectivo. Resultados: Se hallaron 51 expedientes de pacientes a quiénes se realizó HO de enero de 2012 a noviembre de 2015. La prevalencia fue de 17,1/10.000 nacimientos, la incidencia por año fue de 1,7 (2012), 1,7 (2013), 1,4 (2014) y 1,9 (2015) por cada mil nacimientos respectivamente. La prevalencia de HO post-cesárea fue de 25,6/10.000 y en el post-parto de 10,6/10.000. Las variables que alcanzaron significancia entre cirugía programada y de emergencia fue pérdida sanguínea y necesidad de transfusiones sanguíneas. El procedimiento se asocia a anemia en el puerperio 7 veces más y las principales indicaciones para realizar el procedimiento fueron alteración de la adherencia placentaria e hipotonía. Conclusiones: El diagnóstico prenatal de anomalías en la adherencia placentaria, la mejor utilización de hemoderivados y la técnica quirúrgica ha eliminado la mortalidad materna por hemorragia obstétrica masiva en los últimos cuatro años en el Hospital General Dr. Aurelio Valdivieso.
Objective: To determine the incidence, main indications and complications of obstetric hysterectomy in a secondary hospital care to four years to implement the program of prevention and management of obstetric hemorrhage. Methods: Descriptive study of review of clinical records, transversal, analytical and retrospective. Results: 51 cases of patients who obstetric hysterectomy (OH) was held between January 2012 to November 2015. The prevalence was 17.1/10,000. The incidence per year was 1.7 (2012), 1.7 (2013), 1.4 (2014) and 1.9 (2015) per 1000 births, respectively. The prevalence of post-cesarean OH was 25.6/10,000 while postpartum OH was 10.6/10,000. The variables that reached significance between scheduled and emergency surgery was blood loss and need for blood transfusions. The procedure is associated with anemia in the postpartum period 7 times and the main indications for the procedure were alteration abnormal placental adhesion and uterine atony. Conclusions: The prenatal diagnosis of abnormal placental adhesion, better use of blood products and surgical technique has eliminated maternal mortality by massive obstetric hemorrhage in the last four years in the General Hospital Dr. Aurelio Valdivieso.

Background: Toxemia of pregnancy is the leading cause of maternal mortality and is an important factor in fetal wastage. The incidence is high in developing countries with malnutrition, hypoproteinemia, and poor obstetric facilities. Objectives: The present study was undertaken to analyze placental changes in the preeclampsia-eclampsia syndrome with a view to assess the significance of villous abnormalities by histopathological methods because these changes serve as a guide to the duration and severity of disease. Gross abnormalities noted were the placental infarcts, retroplacental hematoma, and calcification. Results: The striking villous abnormalities observed in the study group were cytotrophoblastic proliferation (86%), thickening of the villous basement membranes (95.23%), increase in syncytial knots (90.4%), villous stromal fibrosis (92%), fibrinoid necrosis (97.82%), endarteritis obliterans (53.96%), decreased villous vascularity, and paucity of vasculosyncytial membranes (93.65%). Conclusions: The gross abnormalities and villous lesions in the preeclampsia (P < 0.001) and eclampsia syndrome (P < 0.05) were significant.

OBJECTIVE: To determine the prevalence of placental pathology among low birthweight infants delivered at Srinagarind Hospital. MATERIAL AND METHOD: Descriptive study of 114 placentas from infants weighing between 500 and 2,499 grams delivered between June 2002 and June 2004 in the labour room, Srinagarind Hospital. Placentas from low birthweight infants were examined by a perinatal pathologist in the surgical pathology room, department of pathology, faculty of medicine, Khon Kaen University. The demographic data of the mothers, the gestational age of the infants by obstetric information and according to the Ballard score and placental examinations were collected and analyzed. The placental examinations included both macroscopic and microscopic studies. RESULTS: The prevalence of placental pathology in low birthweight infants was 80.7%. The four types of placental pathology were an increased placental to fetal weight ratio, infarction, vascular abnormalities of the decidua, and inflammation in 64.1, 30.4, 20.6 and 18.5 percent, respectively. CONCLUSION: All placentas of low birthweight infants should be studied for potential pathologies.

Se analiza la tasa de mortalidad fetal tardía (TMFT) en Chile entre los años 1990-1996. Hay un significativo descenso de ella y de los nacimientos. La TMFT del período fue de 5,2/1.000 nacidos vivos. Las TMFT fueron significativamente más altas en las madres mayores de 34 años (7,9/1.000), en el bajo peso al nacer (57,2/1.000) y en la prematurez (58,2/1.000). el 42,3 por ciento y el 44,7 por ciento de los mortinatos pesaban más de 2.500 g y eran mayores de 36 semanas, lo que se interpreta como un subdiagnóstico de retardo del crecimiento intrauterino. Las causas más importantes de mortalidad fetal tardía corresponden a patología placentaria y de los anexos ovulares, hipoxia intrauterina, patología materna pregestacional y malformaciones congénitas

A great majority of death-in-utero in this country may be due to placental insufficiency. This problem may have some correlation between parity, maternal age and weight of placenta. The present work has been attempted towards determination of the morphological and histological aspect of human full-term placentae and their relation with different parity and age group of mothers. The weight, size and number of cotyledons of placentae were found to be directly proportional to the maternal age and parity. No definite change in histology was observed except for the increase in fibrinoid degenerations in the stem villi and calcium deposition on the septal region of the placentae. These changes may have some important bearing on the placental insufficiency in higher age group and parity of mother.
